Description (from the catalogue, unverified)
Whether a number has a WhatsApp account, and nothing else: the cheapest way to clean a list before paying for profiles. /v1/profile gives the same answer plus the account's details. Query param: phone, with country code (e.g. +14155552671). Every answer is charged, “not on WhatsApp” included; a lookup WhatsApp does not answer is free.
